#[repr(C)]
pub struct RawWireUnion { /* private fields */ }

A raw FIDL union

Implementations

impl RawWireUnion

pub fn encode_absent(out: &mut MaybeUninit<RawWireUnion>)

Encodes that a union is absent in a slot.

pub fn encode_as_static<E, T>( value: &mut T, ord: u64, encoder: &mut E, out: &mut MaybeUninit<RawWireUnion>, ) -> Result<(), EncodeError>

where E: InternalHandleEncoder + ?Sized, T: Encode<E>,

Encodes a 'static value and ordinal in a slot.

pub fn encode_as<E, T>( value: &mut T, ord: u64, encoder: &mut E, out: &mut MaybeUninit<RawWireUnion>, ) -> Result<(), EncodeError>

where E: Encoder + ?Sized, T: Encode<E>,

Encodes a value and ordinal in a slot.

pub fn encoded_ordinal(slot: Slot<'_, RawWireUnion>) -> u64

Returns the ordinal of the encoded value.

pub fn decode_absent(slot: Slot<'_, RawWireUnion>) -> Result<(), DecodeError>

Decodes an absent union from a slot.

pub fn decode_unknown_static<D>( slot: Slot<'_, RawWireUnion>, decoder: &mut D, ) -> Result<(), DecodeError>

where D: InternalHandleDecoder + ?Sized,

Decodes an unknown 'static value from a union.

The handles owned by the unknown value are discarded.

pub fn decode_unknown<D>( slot: Slot<'_, RawWireUnion>, decoder: &mut D, ) -> Result<(), DecodeError>

where D: Decoder + ?Sized,

Decodes an unknown value from a union.

The handles owned by the unknown value are discarded.

pub fn decode_as_static<D, T>( slot: Slot<'_, RawWireUnion>, decoder: &mut D, ) -> Result<(), DecodeError>

where D: InternalHandleDecoder + ?Sized, T: Decode<D>,

Decodes the typed 'static value in a union.

pub fn decode_as<D, T>( slot: Slot<'_, RawWireUnion>, decoder: &mut D, ) -> Result<(), DecodeError>

where D: Decoder + ?Sized, T: Decode<D>,

Decodes the typed value in a union.

pub fn absent() -> RawWireUnion

The absent optional union.

pub fn is_some(&self) -> bool

Returns whether the union contains a value.

pub fn is_none(&self) -> bool

Returns whether the union is empty.

pub fn ordinal(&self) -> u64

Returns the ordinal of the union.

pub fn get(&self) -> &WireEnvelope

Gets a reference to the envelope underlying the union.

pub unsafe fn clone_unchecked<T>(&self) -> RawWireUnion

where T: Clone,

Clones the union, assuming that it contains an inline T.

Safety

The union must have been successfully decoded as a T.

impl ZeroPadding for RawWireUnion

fn zero_padding(_: &mut MaybeUninit<RawWireUnion>)
